Post-suspension-rebuild driving comfort?

Hey guys, I'm about to start my job soon (Yeah!:supz:) and the first thing I want to get once I get paid is a suspension rebuild kit and front sway bar kit for my '70 318 Duster. I'm wondering, will the car be any less comfortable if I go with polygraphite bushings and install a sway bar? Also, what size front sway bar should I go with?
